Stock Returns and Option Prices: An Exploratory Study

This study is an investigation of estimates of expected stock returns implicit in option data. The Lee-Rao-Auchmuty option valuation model provides a unique opportunity to examine whether return measurements derived by nonlinear estimation techniques show any correlation with future stock returns. During the short period covered in this study, the Lee-Rao-Auchmuty estimates give preliminary indications that they are better predictors of actual stock returns than are estimates obtained from historical data.
